@cf4 has recently received the Telstra 5G Home Modem, and has written a manual and also performed some test. A few of his findings.
The service does not support servers which means that some old style IP cameras and security systems will not be able to be accessed remotely. Even devices that support IPv6 can not be viewed remotely as I can find no way for allowing access through modems firewall. All port forwarding and special service access is disabled in 5G mode.
Some older devices require tinkering with the modem's WiFi settings before they will connect (Change Authentication mode or change Wireless mode to g/n or a/n/ac).
Some device want connect to modem's WiFi, no mater what changes are made to WiFi settings or connect at a greatly reduced speed (example one devices connect to Telstra Gen 2 Modem at 20 Mbps but only connects to AW1000 WiFi at 1.5 Mbps.
Could not get Bridge mode to work in modem.
